The text messages between the two FBI employees, counterintelligence agent Peter Strzok and lawyer Lisa Page, are among a larger batch of messages that were not saved by the FBI because of a software glitch on some Samsung phones.

Trump's tweets came after Fox News host Sean Hannity addressed the issue on his Tuesday night show, though it is unclear if that is what prompted him to tweet. Trump is known to be an avid watcher of Fox News and often comments on matters shortly after they are addressed on air.

It was unclear if Trump was being sarcastic in his tweet. The president has been critical in the past of the DOJ and FBI in its handling of the Russia investigation.

The text messages have come into focus as some Republicans raise concerns about political bias among the ranks of the FBI.
